I think that lake has clear water --- if so you will have to fish a little deeper ... In unknown waters high end electronics will help find fish, but fish like Smallmouth Bass and Saucer inhabit those waters as well as Crappie. Tackle shops can help also-- what areas of the lake are better for fishing and Topo maps ... Local Guides -- some of them will tell area, Depth, and best colors for those waters but many wont. A good Guide will try to help and a half day with him could be well spent
